Small-school sleepers to keep an eye on at the combine

Adderley is a versatile defensive back who could climb to the end of the first round with a good combine. Some teams see him as a cornerback, but Adderley was highly productive in college and has good speed.

A talented athlete out of Washburn, Ballentine flashed at the Senior Bowl and has already seen his stock climb. He's a potential second-day draftee with ability to contribute immediately on special teams.

Bell is a tall and productive defensive back at 6-foot-3, finishing last season with 87 tackles and three interceptions. The college production alone could make him an early third-day pick.

Brown returned from a torn ACL last season and was able to put himself on NFL radars. He's improved rapidly after moving over from wideout. Brown also happens to be the nephew of former NFL running back Herschel Walker.

Bunting had nine interceptions over the last three seasons for Central Michigan. He was arguably the Chippewas' best defensive player and could go early on the third day.

Crosby is coming off two huge seasons, with 11 sacks in 2017 and 7.5 sacks and 70 tackles last year. He has good size at 6-foot-5 and could be a nice developmental prospect.

A Pitt transfer, Davis had 80 tackles and 5.5 sacks in only 12 games last season. He's converted from linebacker to defensive end, and the lack of size probably puts him toward the end of the draft.

Davis has experience at both guard and tackle in college but more likely profiles as a guard at the next level. He has a chance to play quickly in the NFL and can boost his status with a solid combine.

Doss was a highly productive college player who could be a second-day pick if he performs at the combine. He has NFL height at 6-foot-3 and had elite numbers in each of the last two seasons.

Granderson's productivity dropped off last season after finishing with 78 tackles and 8.5 sacks in his junior campaign. He can solidify his status as a third-day pick with a strong combine.

Howard is relatively inexperienced on the offensive line, but he has great athleticism as a former basketball player. He could be an early third-day pick with what's expected to be a good combine performance.

Jackson has superb raw talent but probably wasn't ready to make the jump to the NFL. A stout 6-foot-7 quarterback with a strong arm and mobility, Jackson completed only 55.3 percent of his passes in his junior season but had 3,131 yards passing and 28 touchdowns. He will need a year or two of seasoning and could remind scouts of former Ohio State quarterback Cardale Jones.

Hanks' production fell off last season, but he had more than 100 tackles in three straight seasons as a stalwart on New Mexico State's defense. He's likely a third-day pick but could move up if he stacks up well against big-school linebackers at the combine.

At worst, Henderson looks like a potential third-down back with blazing speed and decent hands. He averaged 8.9 yards per carry in consecutive seasons for the Tigers and finished last season with 1,909 yards rushing and 25 total touchdowns.

Oliver is well behind the top tier of tight ends at the combine but was able to put himself on the radar with 56 catches for 709 yards and four touchdowns last season. He could fit in as a No. 2 tight end immediately with his good ball skills.

Pipkins has left tackle experience at Sioux Falls, though it remains to be seen if he's ready to contribute in the NFL. He's likely to be a third-day pick, with a strong combine performance.

The nephew of former NFL Super Bowl MVP quarterback Mark Rypien, Brett was a four-year starter at Boise. He capped off his career with more than 13,000 yards passing and 90 touchdowns, including 30 touchdown passes last season. The production will certainly get him drafted, though he probably profiles best as a No. 2.

A 300-pound running back in high school who can do backflips, Saunders already made headlines for staying at the Senior Bowl while his fiancee was giving birth. His athleticism makes him an interesting prospect, though his lack of height, at 6-foot-0, probably puts him in Rounds 4-5.

Scharping could be picked in the draft's second day, with a solid history starting at both guard and tackle for Northern Illinois. He has ample size to play anywhere on the line.

Singletary was a star in Lane Kiffin's offense and finished his three-year career with 4,287 yards rushing and 66 rushing touchdowns. His lack of size and big workload are concerns, but the productive Singletary can push himself to the second round with a good combine.

Carson Wentz's replacement at North Dakota State, Stick is hoping to have his name called in the late rounds. He was a mobile and productive quarterback in college but probably lacks the arm strength to be anything more than a backup.

Udoh is a smart and huge right tackle prospect, listed at nearly 340 pounds. He will probably need some time to develop after facing inferior competition in college, but the right team could find an eventual starter on the third day of the draft.

An edge rusher with a legitimate shot to go in the first round, Ximines improved in every season at Old Dominion. He finished his career with 32.5 sacks, including 11.5 sacks in his senior season. The combine will be pivotal for his draft stock.

Ya-Sin is a potential draft unicorn who was highly productive last season after transferring from Presbyterian. He has the physical traits scouts dream about, so it wouldn't be a surprise if he shoots up draft boards after the combine. A late first-round selection isn't out of the question.
